Application Summary AI generated
This standard specifies the method for individually assessing the appearance quality of yarns made from cotton, man-made fibers, or their blends by winding them onto a black board. It is applied in textile manufacturing and quality control laboratories to evaluate yarn evenness, neps, and surface defects for individual yarn samples. The method is used to determine whether a specific yarn lot meets appearance quality requirements for subsequent fabric production.
